Description

Technical Field

[0001] The utility model relates to a three-way material distribution funnel of a belt conveyor which is not easy to be blocked and belongs to the technical field of belt conveyor equipment. Background Art

[0002] Belt conveyors are widely used in bulk material transportation in ports, power plants, mines and other units. Belt conveyors need to be assisted by a combination of multiple conveyor belts in the process of transporting materials in order to complete the material transportation work with maximum efficiency. During the conversion of different conveyor belts, the operator needs to adjust the position of the flap in the three-way funnel in the transfer tower to change the direction of material diversion and divert the materials transported by the upstream belt conveyor to the corresponding downstream belt conveyor.

[0003] At present, fan-shaped material distribution flaps are generally used in three-way funnels. The material distribution plate of the fan-shaped flap is welded and fixed on a square rotating shaft, and the swing is realized by a rocker arm connected to the rotating shaft. When observed from the side, the movement trajectory of the flap looks like an unfolded folding fan, so this form of material distribution flap is called a fan-shaped flap.

[0004] The direction of the material conveyed by the upstream belt conveyor to the three-way funnel is fixed, so when passing one side of the fan-shaped flap, it will slide along the flap surface into a funnel leading to the downstream belt conveyor; and when passing the other side of the fan-shaped flap, the material will hit the flap surface at an angle close to 90° to slow down and then change direction, sliding into another funnel leading to the downstream belt conveyor. At this time, the redirected material will first slow down and then fall, and the flow rate of the material will decrease. If the transported material is sticky or the flow rate is large, the three-way funnel is prone to blockage, resulting in problems such as funnel return and conveyor belt shutdown. When the blockage is serious, it may even collapse the transfer tower, causing great economic losses. Therefore, it is necessary to design a three-way material distribution funnel that is not easy to block, improve the working efficiency of the belt conveyor, and ensure equipment safety.

[0008] The above-mentioned three-way distributing funnel which is not easy to be clogged, the rotating shaft driving device includes a connecting plate, a connecting pin shaft, an electric push rod, a push rod pin shaft, a push rod base, and a push rod platform. The connecting plate is an L-shaped long plate. The upper end of the connecting plate is fixedly connected to the square shaft of the rotating shaft of the flap.
